Serial No. 782,020 v 3 Claims. (01. 107-30) This invention relates to a chloroether product derived from 4-vinylcyclohexene by causing 4-vinylcyclohexene to interact with ethylene chlorohydrin at an elevated temperaturein the presence of an acid-acting catalyst and to its preparation. The nature of the reaction product and the details of its preparation are more fully set out hereinbelow. r r

We have found that 4-vinylcyclohexene will form an ether product when it is caused to interact with ethylene chlorohydrin in the presence of an acid-acting catalyst at an elevated temperature. f Thus, according to the invention there is provided a novel product, and a process for its preparation, from 4-vinylcyclohexene by causing 4- vinylcyclohexene to interact with ethylene chlorohydrin in presence of anacid-acting catalyst at elevated temperature.

The following examples serve to illustrate th invention:

Example I Anhydrous ethylene chlorohydrin (2.0 mole 161 g.) was heated to 100 C. and 3 ml. of conc. H-SO4 added. One mol (130 ml. 108 g.) of 4-vinylcynow cooled to room temperature and sufiicient NaOI-I added to neutralize the sulfuric acid. .The

than sulfuric acid. The reaction was carried out at 75 C.'for five hours and yielded on distillation 69.5 g. of a mixture of ethylene chlorohydrin and 4-vinylcyclohexene, 34.1 g. of the desired beta-chloroether, corresponding to a yield of 18%, 18.5 g. of a higher boiling product and 16.5 g. residue.

The proportions of the reactants 4-vinylcyclohexene and ethylene chlorohydrin can be within the, range of 0.5 mole to 5.0 moles of ethylene chlorohydrin to one mole of ii-vinylcyclohexene.

mixture was diluted with benzene and refluxed under a Dean-Stark type water trap until dry. The mixture was cooled, filtered from meson and distilled. There was obtained 160.3 g. of a.

mixture of vinylcyclohexene and ethylene chloro hydrin, estimated from its refractive index to contain 73.4 g. of vinylcyclohexene; 33.9, g. of the vinylcyclohexene p-chloroethyl ether, .8. P. 45-100 (3mm. Hg); 46.1 g. of a higher cut, 8. P. 110-185 (3 mm. Hg); and 17.2 g. of a dark soft polymeric residue.

When redistilled, the ether boils at 90-92" (3 mm. Hg) 1a,," 1.4756.

The temperature during the reaction can vary in the range 50 C.-150 C.

Other acid-acting catalysts than those mentioned in the examples can be used. Thus, stannic chloride or boron trifluoride can be used.

The product of this invention also has use as a plasticizer, softener and as a chemical intermediate for further synthesis.

We have also found that the chloroethyl ether product of 4-vinylcyclohexene possesses insecticidal activity against the common house fly.

Thus, when a 5% solution of the product in "Deobase." a deodorized kerosene, was tested by the standard Peet Grady method the following results were obtained.

vided a novel insecticide composition having as at least one of its essential active ingredients the aforesaid chloroether product. According to the invention the chloroether product is admixed with a carrier which can be that above-mentioned or any of the other carriers, whether solids,

Example It The procedure of Example I was followed, except that 0.2 mol (28.4 g.) of boron triiiuorideliquids, emulsions or gases, which are well known in the art.

We claim:

A novel insecticidal composition of matter comprising a minorportion of the beta-chloroethyl ether reaction product obtained upon causing from 0.5 to 5 moles of ethylene chlorohydrin to interact with one mole of 4-vinylcyclohexene ethyl ether complex was used as a catalyst rather at a temperature of from 50 C. to C. in the 0,580,000 1 3 I 4 presence of on acid-Mun: catciyct. and I. mcu m r rtion oi kerosene. 2 5M composition according tociaim 1 whacmm mm M m n "I iii: of this potent: in the acid-acting cataiyct is sulfuric acid.
